The one that is at the right of 706-01-04, it is the write button for the entire block

OK, I did not see your previous message whare you confirm that your current value is indeed 009B 0000 50FB.

All you have to do is to edit this value directly and change the last four digits: 50FB -> 40E8. Once done, hit the "write button at the right side of this module. The software will ask you to turn off ignition and to turn it on again. Finally, once ignition is back on, press the" stop "button at the bottom left , and disconnect forscan. You are done and the TSR should be working

Zitat von ChrizZ Mx

yes Tsr

Once connected with the car and forscan in the status of your previous picture:

- Press the "configuration and programmin" button (at the left side of the screen, the 3rd starting from the bottom). Then select the entry that says "FSC Module Configuration (Data As Built) and hit the "play" button that is at the bottom left.
- If the software tells you to change the position of the OBD adaptew switch, do it). Also, the software will open a warning dialog telling you that it is risky to change as built configurations if you don't know what you are doing. Press OK and let the software to read the configuration
- A new screen will open showing the current values of the FSC module chains. I want you to read and note the current values of chain 706-01-02 and report them to me. Most likely you should have this: 009B 0000 50FB . Please confirm and I will tell you the new value that you need to input. Meanwhile, stop the service and cancel the operation so you do not make any changes.

Okay as far as I have now connected everything. The car is paired, but yes, that was it. I bought a license and installed the driver

OK, what do you wand to change? Activate traffic sign recognition (TSR)?

Salü ChrizZ,
That's exactly how I feel. Especially since with translations there is always a risk of what goes wrong.
I know that from the English / German meetings in the shop.
Hopefully there will still be a social frorum friend where we "ignorant" find the path to enlightenment and less
Speed camera photos shows. : saint:

I understand that this may seem intimidating to you, and I am sorry that I cannot give instructions in German. I have done my best to keep you updated on what can be done and how to do it, but of course it is a complex process that involves configuring and using hardware and software and some excel datasheet interpretation. Therefore, it is difficult to give a foolproof simple instruction that can be followed blindly by anyone.

About 80% of the "difficulty" is to get a computer ready with the necessary software (Forscan) and a functional communication bridge with the car (the OBDII device). This involves downloading the software, getting a license, purchasing the correct OBD device, and install the drivers so it is functional to communicate with the car. This is well explained in this video (also in english but easy to follow), and also you can view the main interface and working procedures with forscan:

Once you have that, you have two options:

- If you are curious and want to learn and understand what you are doing, follow my previous instructions on the downloading of the coding template for mazda vehicles, where you can see the different configuration values and apply them directly. See the other threads to learn what can be changed for your model/year car, ask there, and be ready to experiment.
- If you don't want to complicate your life and you are not confident enough, just read the values of the modules that code for the specific functions that work well and one of us will calculate the changes that you must apply. It is a 2 minute procedure. Post here or PM if you want.

Yes exactly that function. I know that it is available on the US market so it bothers me a lot that Mazda does not show it on the EU models. Makes no sense to me. And as I'm used to it from my BMW I kinda miss it in the MX-5.
Unfortunately I don't have access to any other Mazda cars but maybe it would help if I send you values of my car?

Unfortunately, since all EU cars have this limitation, we are onto unexplored territory here. If you are willing to experiment a little, there are some insights that this function is coded in chain 720-04-35 (IC module). However, it seems that the effect of individual bytes within this chain is not decoded and we do not know how to activate the ADL. Mx5 sold in EU have this value or very similar: 720-04-35: 9024 6500 0079

M2/Cx-3/Mx5 cars from other markets that have ADL activate have these values:

- 720-04-35: 82AC 6520 0013
- 720-04-35: 83AC 6520 0014
- 720-04-35: 8BBA 6520 002A (mx5 US 2020 Grand Touring)

It appears that changing the entire chain for one of the above strings could activate ADL, but it is not clear if this could deactivate other functions depending on the market (things like automatic rain sensors, etc). Since these are accessory trim functions, there is little risk trying and you can roll back to your original values at any time.

If you are willing to experiment, please note that coding IC module is a little more complicated than what you did to activate TSR. This is because IC module has a global checksum protection that prevents changes in certain values. The best way is to proceed as follows:

1- Download your complete "as built" data from mazda with your VIN data using the mazda as built search engine: https://www5.b2b.mazda.co.jp/a…ndexTaskFlow.xml&direct=1
2- Open the .ab file with a text editor, and copy all the values between the <CCC_DATA> tags (at the end of the file)
3- Paste these values in the excel template, in the sheet named "CCC converter" (last one) in cell B1 (the instructions are in a box in this sheet)
4- Copy the 53 values of the column F and paste them in the sheet "IC Mazda 2, Cx3" in cell A7. This will populate this sheet with all your current configuration values,
5- Edit the values in 720-04-35 with forscan as discussed above, but do not save yet.
6- Note that after these edits, there is a new checksum calculated in the excel, in chain 720-04-01 in this same IC module. This value needs to be edited in the car before saving the changes, otherwise the edits in the IC module will give errors and will not be saved.

Please report back if you try and achieve activation of the ADL. Note that after doing the changes, it could be necessary to reset the function in the MZD in the new menu that should appear, before the function works normally.

Hi @Baldo Mero I have one more question. I wanted to enable the Auto Door Lock function but when connected to the car FORScan doesn't show the RBCM Module. Do you ever had this problem or know why it is not showing?

You are talking about locking the doors automatically when driving >20kmh, aren't you?. Not about the keyless entry/ auto door locking when the key is out of range....

Hi Bar!

The excel template is mainly based on functions of the Mazda 3 and not all the modules and functions are present in the Mx5. The Mx5 is, indeed, more similar in the ECU structure to the Cx-3 and Mazda 2.

One of the differences is the absence of chains 7B7-XX-XX in the Mx5. We are researching if some of the functions coded in this module in other models are assumed by other addresses elsewhere in mx5.

You may want to experiment with the values of BCMM module, 726-01-01, which also control some parameters of the auto-lock function. However, it seems that all EU cars have this option locked whereas American cars can be configured. SO I guess it is a question of experimenting and comparing the values with those of cars from other markets.

@Baldo Mero the TSR activation worked perfectly, thanks again If you should ever happen to be in Hamburg I owe you a beer

Glad that it worked!. I'll remember about the beer if in Hamburg Out of curiosity, which OBDII adapter did you use?

Zitat von Torben

@ MX593 @beetyii

Hehe thanks. As I said, there is still a prototype and was happy that it was finally displayed in the car. I'm still working on the ID-tire assignment, because initially the values come in unordered.
Two guys from the Spider forum supported me with the circuit board and the protocol for communication with the car.

In simple terms:
I have an Arduino microprocessor on the UBS connector. The app and an exe that can communicate with the microprocessor are installed on the MZD.
The microprocessor has a radio receiver (CC1101) for 433 MHz signals such as those from the tire pressure sensors. It was a big task to decipher these signals.

What is required:
- the app (in development)
- Arduino Nano and a CC1101 receiver.

If you can solder (or if you want to work with a breadboard or cable connections) and are familiar with Arduino, you can build it yourself. I can provide the code for the Arduino etc.
I can't (yet) put a price on it. I just feel a bit how big the demand would be.

There are still a few construction sites on the app:
- Design adjustments for vehicles other than the 124 Spider - Designer: if someone plan views MX-5 (also RF) can possibly create in different colors even like to contact me!
- ID tire assignment
- Installer (USB stick like Speedometer app)
- Compatibility with the different firmware (so far only 56.xxx tested, problems with 70.xxx + suspected)

I can also make the app available, but for the current beta test it has to be installed parallel to the Speedometer app, which at the moment only works via SSH / FTP and the IDs have to be assigned via SSH.

@ MX593 Do you use this here on the Raspi? https://github.com/merbanan/rtl_433
The code "tpms_abarth124" is mine, so you should be able to receive your sensors (I would appreciate your feedback). The sensors react to movement or pressure changes> +/- 10% (~ 0.2 bar) and then send 2 or 3 times in quick succession. And then a couple of times every 4 hours.

That is awesome @ 'Torben', huge task

From what I hear root access to MZD is blocked in current firmware versions, tweaks nee to be installed hacking through the serial port. Would this be the case for your apps as well?
